I agree 100%, when i became plumbing inspector i banned them. Also garburators .Personally I hate the fact that they approved cpvc for supply lines in a home. Twice in the same home I have had the pipes shatter when just closing the under sink stops to replace faucets. I would recomend that if you're changing faucets on a home with cpvc to shut off the whole house shutoff! That could save a LOT of headaches.
